Ill give an example, suppose I want to factor to solve for the roots $$-x^3+9x^2-15x+2=0$$ Now; I know there are a few general methods. I know one way is to factor by grouping, but this cannot be done in …

Jul 19, 2018 · Can someone help me factor $\;2x^3-1=0\;$ ? I've never known how to factor cubic functions. There should be cubic roots involved.

A cubic polynomial can only factor into the product of a linear and a quadratic factor (which itself might factor further). So if it has no linear factors, it's already irreducible.

I want to know how one would go about solving an unfactorable cubic. I know how to factor cubics to solve them, but I do not know what to do if I cannot factor it. For example, if I have to solve f...

Feb 28, 2016 · Proceed to factor the polynomial to find the other non-rational roots. I note that if you allow complex roots that are with many cube roots and other radicals, then all cubic polynomials and …

The way to factor a four-term polynomial like this is to apply Rational Root Theorem along with synthetic division or substitution to determine whether a rational root works for the polynomial or not.
